Question

sabe a = 3 1/4 - 5/3 e b= 1 1/3 - 1/2, calcule a+b

Answer 1

A = $3 \frac{1}{4} -\frac{5}{3}$

B = $1\frac{1}{3} -\frac{1}{2}$

A + B = $3 \frac{1}{4} -\frac{5}{3} + 1\frac{1}{3} -\frac{1}{2}\\\\ 3\frac{1}{4}-\frac{5+1}{3}-\frac{1}{2}\\\\\frac{(3*4)+1}{4}-\frac{6}{3}-\frac{1}{2}\\\\\frac{13}{4}-\frac{6}{3}-\frac{1}{2}\\\\\frac{39-24-6}{12}=\frac{9}{12}=\frac{3}{4}$
